ENGINE RUNS HOT 

 

 

POSSIBLE FAULT 

REMEDY 

1. 

Water level low in cooling system. 

Refill and check all coolant hoses  

 

 

and clips for safety. 

2. 

Air leaks in induction system. 

Check the joints between: 

 

 

a) The cylinder head-and-intake manifold 

 

 

b) The carburettor-and-intake manifold. 

 

 

If necessary, fit new joints/tighten nuts. 

3. 

Carburettor(s) setting faulty. 

Adjust carburettor(s). 

4. 

Choke in ‘rich’ position. 

Return choke-control to correct position. 

5. 

Defective heat exchanger or oil cooler. 

a) Clear blockage (back -flush). 

 

 

b) Fit new heat exchanger or oil cooler. 

6. 

Oil diluted or of incorrect grade. 

Drain oil system and refill  

 

 

with correct grade of oil. 

7. 

Faulty thermostat. 

Test thermostat – renew if necessary. 

8. 

Insufficient differential pressure  

Increase pump pressure to minimum  

 

in raw water system. 

3 bar differential. 

9. 

Blocked strainer in raw water feed  

Remove strainer and clean. 

 

from manifold. 

 

DIFFICULT STARTING 

 
1. 

Weak spark due to: 

 

a) Faulty spark plugs. 

Fit new spark plugs. 

 

b) Wet or fouled spark plugs. 

Clean or renew. 

2. 

Low compression. 

Check for: 

 

 

a) Correct valve clearance. 

 

 

b) Loose cylinder head. 

 

 

c) Blown cylinder-head gasket. 

 

 

d) Loose spark plug(s). 

 

 

e) Damaged or burnt valves. 

 

 

f) Worn piston rings. 

 

 

g) Worn cylinder bores.
